ABSTRACT:
An adjustable wide angle inside rear view mirror includes a stationary central mirror and a pair of extensible side mirrors which can be pulled out so that the driver has a view of other vehicles in the "blind spots" on either side of a conventional rear view mirror. The side mirrors are interconnected so that both side mirrors are extended when either one of the side mirrors is extended manually. The extension of the side mirrors is continuously adjustable, but the amount of travel is limited so that the side mirrors can be pulled out only about three-quarters of their length. The wide angle rear view mirror can be retracted to permit the driver to adjust the position of the car's sun visors, and then reextended.
